    Re: Finally Back....2.5L S14


    Congratulations on your 2.5L

    I'm glad everything is fine with your engine now. So, what are your initial thoughts? (i'm sure you still have a while to break in??) Worth the money? I hope it was everything you expected it to be and more!

      Congrats Mike, I'm sure it's a blast to drive. How about a dyno chart after it's broken in?

          Nice rims

          like everybody else wants to know, what did you have him do? I want to do my own, but after talking to him a couple of times, i'm thinking of letting him undertake my car:borg:

            I'll let Mike give a full list, but it rivals most/all motors on this board with the exception of EVOIII, and I still think he is running hotter cams in his S14 than whats in your "puny" S14.

            P.S. That Puny part was a joke.

              not only that, Mike is running alpha N with a cf airbox

              I think there are a few people on this board who have motors
              to compete

                Enough of the crap :rolleyes:

                Can someone please tell us what kind of 2.5L build he has??

                Talk is great, but I'd rather wait until the dyno sheet comes in before the talk begins.

                    It's a 2.5L with a fully forged 11.35:1 bottomend, lots of head work, really hot cams and all the good stuff. It's a race motor, intende for 100+ octane. I'll let Mike tell everything else.

                      Thank you Stu,

                      Sounds like a nice track beast considering it requires 100octane! Damn, looking forward to a write up and dyno later, must be quite a beast.

                        not sure if youre referring to Jefrems motor.
                        Jefrems motor has 13.5:1 compression and 284/276 cams
                        with alpha N and DTM intake, dry sump, and numerous other
                        things. the head work im not sure about.
                        the cams are not that hot, which does make his power impressive.

                          Wow, a dry sump to extinguish all those thoughts of losing an engine to oil starvation That is awesome. Hey John, does having a dry sump provide any hp/tq advantages, or just insurance against oil deprivation?? Thanks.

                            Dry sump systems typically give you about 2 - 5 % better engine efficency. So figure at least another 10 hp on a built 2.5 S14 motor. Excess oil around the crankshaft in a wet sump can get on the shaft and cut horsepower. Some people claim improvements of as much as 15 horsepower by switching to a dry sump.


                            In a wet sump, turning, braking and acceleration can cause the oil to pool on one side of the engine. This sloshing can dip the crankshaft into the oil as it turns or uncover the pump's pick-up tube.

                            Dry sump's rule.

                            I just wish the NSX had a dry sump.

                            Hell the E39 M5 has a factory semi-dry sump system.

                              Can't wait to see some dyno runs

                              The problems he had were unrelated to the engine- i just wanted to add that. The shop installing the motor also installed anextensive list of other chasses-related mods.. when leaving the shop the radiator apparently gave out, but i don't know the details. I think it was just coincidence that it failed when leaving the shop.
